I LAMP-BURNER. I A I Specicaton. of Letters Patent.

Patented Dec. 25, 190e.

Application filed May 3l, 1906. Serial NoL 319,623.

' T0 all whom t may concern:

Be it known that I, JAMES HOLLIS MORRI- soN, a citizen of the United States, residing at Dayton, in the lcounty of Montgomery and State of Ohio, haveinvented a new and useful Lamp-Burner, of which the following is a specification. j 1 y This invention relates to lamp-burners.

In my United4 States' Patent No. 827,812, dated August 7, 1906, for alamp-burner :Ihave described and claimed means by which the height and width of the flame of an oil-burner may be increased by the employment of aircurrents.

The: object of present invention is to provide simplified and im roved means for .l accom -lishing the result a ove set forth.

Wit the foregoing and other objects in view, Iwhich will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the ldetails of construction hereinafter described and claimed.

In the accompanying drawings, forming a part ofithis specification, Figure 1 is a perspective view of a conventional form of lampburner equipped with the improvements of the present invention, the dome ofthe burner being partly broken away adjacent to the end of the iame-slot. Fig. 2 is a vertical section through the construction illustrated in Fig. 1.` Fig. 3 is a vertical section through the modified construction. Fig. 4 is a plan view of the blank shown in Fig. 3.

Lilie reference-numerals indicate corres onding parts in the differentiigures of the rawings. l

The improvements of my present invention can be readily used in connection with any old and well-known form of oil-burner.

In order to convey a clear understanding of the invention, I have illustrated it in connection with anl ordinary form of oil-burner com rising a threaded feed-wheel chamber 1, in w -ch is mounted the usual'feed-wheel for the wick; a su porting-platel 2, suitably manner through the feed-wheel chamber 1,

the supporting-plate`2 `is formed with a pair of Vair-Inlet openings 6 which. serveto permit the entrance of two columns of air at4 opElosite ends of the wick-tube. Dis osed wit fn the dome 3 is a pair of inward y-extending ,guide-plates 7, each of which is formed with .a U-shaped slot 8into the open end v.of which partially extends the wick-tube 5. The U- shaped yslots 8 in the guide-plates 7 constitute means located. above the supportingplate 2 for producing currents of air at the ends of the wick-tube, the function of these currents of air being to cool the ends of the wick, so as to prevent vit from charring or burning up rapidly, as well as to `cause the wick to burn more brightly and to give the flame an upward impetus, which increases its height and illuminating ower.

f It will be obvious that 1f the columns of air passing through the inlet openings or passages 6 in the supporting-plate should become broken up before they reach the upper end of the wick-tube the guide-plates 7, with their U-shaped slots 8 at the ends of the wick-tube', would serve to form the air again in the columns. n By using the guideplates 7, which, as will be apparent, are extremely simple and inexpensive in construction, as well as capable of being readily attached to any form of burner, I am enabled to dispense with the use of the U- shaped airguide tubes shown in my before-mentioned patent.

In addition to roviding means located above the supporting-plate fory forming the air into columns, and thus increasing the height of the flame, it is desirable also to provide means for broadening the flame, so as to further increase its illuminating power.

In my former patent I have described tubes or air-guides which are secured to the Vinterior of the dome 3 and are provided with outwardly and upwardly directed ends, which produce two converging columns of air, the tendency of which is to broaden the ame.

My' present invention provides simple and inexpensive means located at the ends of the flame-slot for accomplishing this result of broadening the flamel The specific means which I rovide herein consists of a pair of opposltely-extending u wardly-inclined plates 9, which are suitably secured to the outside of the dome 3 adjacent to the ends of the flame-slot 4 by solder or any other IOO IIO

with V-shaped or U-shaped notches having their open ends directed outwardly, as shown clearly in the drawings.

It will be obvious that the improved means which I have provided for forming columns of air at the ends of the wick-tube, so as to increase the height and illuminating power of the iiame and for producing conf verging currents of air by which to broaden the flame, can be easily applied to all conventional forms of burners without necessitating any reconstruction thereof, it being only necessary to provide air inlet ineans in the supporting-plate and to attach the guide-plates 7 and 9 to the dome 3 adjacent yt-o the ends of the flame-slot 4.

It will be apparent that many changes in the precise embodiment of the invention illustrated and described may be made within the scope of the claims without departing from the spirit of the invention or sacrificing any of the advantages. Furthermore, the U-shaped slots 8 in the guide-plate 7, as shown in Fig. 1, in some instances may be widened, as indicated at 8', so as to extend partly along the sides of the wick-tube 5 at the ends thereof, whereby to cause a thin envelop of air to be fed to the sides of the flameat the ends thereof. Moreover, the guide-plates 7 and 9, if desired, may be formed from an integral blank 12, as shown in Fig. 4, said blank being folded at the dotted line 13 and suitably riveted or otherwise secured to the dome 3, as shown in Fig.

-3,Jwith the guideplate 7 extending inward and the Cruide-plate 9 extending outward7 said blaril being preferably formed with notches 14 adjacent to the guide-plate i) to fit the edges of the flame-slot.

In practice it is sometimes found desirable to bend the projecting ends of the guideplate 7 on opposite sides of the U-shaped slot 8, as shown clearly in Fig. 3 of the drawings.

What is claimed is- 1. A lamp-burner comprising a supporting-plate having air-inlets, a wick-tube, a dome having a llame-slot, interiorly-arranged guide-plates extending from said dome at the ends of the `liamesslot, and hav ing U-shaped slots fitting around the ends of the wick-tube, and outwardly and upwardly inclined slotted guide-plates secured to the dome near the ends of the iianieeslot.

2. A lamp-burner comprising a supporting-plate having air-inlets, a wick-tube, a dome having a flame-slot, interiorly-ar ranged guide-plates secured to the dome at the ends of the flame-slot and having slotted ends embracing the ends of the wick-tube, and outwardly and upwardly inclined slotted guide-plates integral with the 'first-nientioned guide-plates and extending through the iiame-slot at the ends thereof.

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in the presence of two witnesses.
